Zeolite ZSM Series
-
ZSM-35
ZSM-35 molecular sieve muaj kev ruaj khov hydrothermal zoo, thermal stability, pore qauv thiab acidity tsim nyog, thiab tuaj yeem siv rau kev xaiv cracking / isomerization ntawm alkanes.
-
ZSM-48
ZSM-48 molecular sieve muaj kev ruaj khov hydrothermal zoo, thermal stability, pore qauv thiab acidity tsim nyog, thiab tuaj yeem siv rau kev xaiv cracking / isomerization ntawm alkanes.

Zsm-23
Tshuaj muaj pes tsawg leeg: |na+n (H2O) 4 | [alnsi24-n o48]-mtt, n< 2
ZSM-23 molecular sieve muaj lub moj khaum MTT topological, uas muaj tsib lub nplhaib uas muaj tswv cuab, rau lub nplhaib uas muaj tswv cuab thiab kaum lub nplhaib uas muaj tswv cuab tib lub sijhawm. Cov qhov me me uas muaj kaum lub nplhaib uas muaj tswv cuab yog cov qhov me me sib luag uas tsis sib txuas ua ke. Lub qhov ntawm kaum lub nplhaib uas muaj tswv cuab yog peb-seem wavy, thiab qhov seem yog teardrop zoo li.
-
ZSM-22
Tshuaj muaj pes tsawg leeg: |na+n (H2O) 4 | [alnsi24-no48]-ton, n < 2
Lub pob txha ZSM-22 muaj cov qauv topological ntau heev, uas suav nrog tsib lub nplhaib uas muaj tswv cuab, rau lub nplhaib uas muaj tswv cuab thiab kaum lub nplhaib uas muaj tswv cuab tib lub sijhawm. Cov qhov me me uas muaj kaum lub nplhaib yog cov qhov sib luag uas tsis sib txuas ua ke, thiab lub qhov yog elliptical.

ZSM-5 Series Zeolites xaiv cov duab
ZSM-5 zeolite siv tau rau kev lag luam petrochemical, kev lag luam tshuaj zoo thiab lwm yam teb vim nws muaj qhov tshwj xeeb peb-seem hla ncaj pore canal, tshwj xeeb zoo li-xaiv crackability, isomerization thiab aromatization muaj peev xwm. Tam sim no, lawv tuaj yeem siv rau FCC catalyst lossis additives uas tuaj yeem txhim kho tus lej octane roj av, hydro/aonhydro dewaxing catalysts thiab unit process xylene isomerization, toluene disproportionation thiab alkylation. Tus lej octane roj av tuaj yeem txhim kho thiab cov ntsiab lus olefin kuj tuaj yeem nce ntxiv yog tias cov zeolites raug ntxiv rau FCC catalyst hauv FBR-FCC reaction. Hauv peb lub tuam txhab, ZSM-5 serial zoo li-xaiv zeolites muaj silica-alumina piv sib txawv, txij li 25 txog 500. Kev faib tawm ntawm cov khoom me me tuaj yeem hloov kho raws li cov neeg siv khoom xav tau. Lub peev xwm isomerization thiab kev ua haujlwm ruaj khov tuaj yeem hloov pauv thaum acidity raug kho los ntawm kev hloov silica-alumina piv raws li koj xav tau.
